AXLE, AX-LETREE, AND BOX OFVEHICLES.

SPECIFICATION forming part of Letters Patent No. 540,119, dated Ma as, 1895. Application filed October 10, 1894. Serial No. 525,485. (No model.) Patented in Victoria August 7, 1894, No, 11,571.

To all whom it may concern:

Be it known that we, JOHN TAGELL, mechanical engineer, residing at Melbourne, GEORGE BERRY EDWARDS, saddletree-manufacturer, residing at 385 Little Lonsdale Street,

Melbourne, and THOMAS DARBY, professional rider, residing at Melbourne, Victoria, citizens of the Colony of Victoria, have invented certain new and useful Improvements in Axles, Axletrees, and Boxes of Vehicles, (for which We have obtained a patent in Victoria, No. 11,571, bearing date August 7, 1894,) of which the following is a specification.

The object of the invention is to provide a cheaper and better method of lubricating the axles of vehicles and portable machinery. Hitherto the means employed have not only been defective but also wasteful of both time and oil. When the latter was required it was either necessary to remove the cap or a portion of it, or probably to remove the whole wheel.

With our improvements there is no cap to cause any inconvenience, while the oil that can be stored within the axle and tree will provide asufficient supply for several months.

Our invention consists of a divided axle and bar or tree (of iron, steel or other metal) the two portions of which are locked together by a sleeve secured by gibs and cotters. Around the inner surface of the axle box which has a closed end and which is secured into the hub of the wheel by a cone and nut, are cast or cut one or more spiral channels. Similar spiral channels are also provided around the axle. A hole is formed up the center of each axle and partially into the bar or tree or the said hole extends right through the bar or tree from axle to axle. When a through hole is provided the oil which has a free passage without any intermediate escape can traverse from one axle through to the other. It is fed into a hole or holes eitherin the top or side of the bar and percolates through a series of small orifices, connected with or unconnected with a channel or channels around the axle. There being a solid end to the axle box no oil can possibly escape.

Referring to the drawings which form a part of this specification, Figure l, (which is a longitudinal view, partly sectionah) shows A, the box; B, the cone on same; 0, the nut; D, the axle; E, the axle bed or tree; F, oilwell in box; G, the central hole through the axle and tree; H, the oil-channels in axle; I,

the oil-channels in box; J, oil-holes through shaft into box; K, sleeve; L, gib and cotter hole; .M, gib; N, cotter; O, spring-cover; P, oil-entrance hole; Q, plug in spring-pl.ate; R, Washer or Washers, and S end of axle-box.

Fig. 2 is a plan of the coupling K,gib M, cotter N, spring-plate O, and plug Q.

Similar letters of reference indicate similar or corresponding parts where they occur in both views.

Our drawings represent an axle and tree in which a hole G traverses the whole length of the complete tree and axles. The oil is admitted into the hole G, through the feed hole or holes P, and is liberated therefrom through the passages J, and the end of the axle D. As it falls through the passages J, it descends onto the wearing portion of the box and finally into the well F. When the oil in the well accumulates above the bottom of the hole G in the axle, it is free again to pass down the passages J, or right across through the two divided bars or trees to the opposite axle when the vehicle oscillates. A complete circulation is thus set up and maintained. When the hole does not traverse the whole length of the tree and axles but extends only from the end of each axle to a short distance inside the collar two oil feed holes P are provided. The two solid intermediate spaces of the tree are locked together either by the sleeve with a gib and cotter as described.

Whether the axle and tree be tubular throughout their length or whether there be an intermediate solid section the two joints of the divided tree do not necessarily meet closely together. A washer or washers of metal, leather or other flexible material or a combination of the same not only assures a tight oil joint but also affords a means of adjusting the distances between the two axles.

It is evident that when the two axle trees are locked together with coned ends and with a gib and cotter as shown in the drawings, no washers are necessary to maintain the oil tight joint. The box is provided with a second oil well at F. The axle has a flange 0' ICO Having now described our invention, what We claim as new, and desire to secure by Let'- ters Patent, isi 1.
